The description focuses on a standard immunoassay technology (CMIA) and does not mention any AI or ML components in the device's operation or data analysis.
No
This device is an in vitro diagnostic (IVD) assay designed to measure levels of phenytoin in human serum or plasma. It is used to monitor drug levels for appropriate therapy, not to provide therapy itself.
Yes
The device measures the quantitative levels of phenytoin in human serum or plasma to help monitor drug levels and ensure appropriate therapy. This quantitative measurement is used in a clinical context to manage a patient's treatment, which falls under diagnostic purposes.
No
The device is an in vitro diagnostic assay that utilizes chemical reactions and hardware (ARCHITECT i System) to measure phenytoin levels, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is "in vitro" and is used for the "quantitative measurement of phenytoin... in human serum or plasma". This clearly indicates that the test is performed outside of the body on biological samples.
- Device Description: The description details a laboratory-based assay using "chemiluminescent microparticle immunoassay (CMIA) technology" and measuring "relative light units (RLUs)". These are characteristic features of in vitro diagnostic tests.
- Purpose: The purpose of the test is to "monitor levels of phenytoin to help ensure appropriate therapy," which is a diagnostic or monitoring function performed on a sample.
Therefore, based on the provided information, the ARCHITECT iPhenytoin assay fits the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The ARCHITECT iPhenytoin assay is an in vitro chemiluminescent microparticle immunoassay (CMIA) for the quantitative measurement of phenytoin, an anticonvulsant drug, in human serum or plasma on the ARCHITECT i System with STAT protocol capability. The measurements obtained are used in monitoring levels of phenytoin to help ensure appropriate therapy.
The ARCHITECT iPhenytoin Calibrators are for the calibration of the ARCHITECT i System with STAT protocol capability when used for the quantitative determination of phenytoin in human serum or plasma.

Device Description
The ARCHITECT iPhenytoin assay is a one-step STAT immunoassay for the quantitative measurement of phenytoin in human serum or plasma using CMIA technology, with flexible assay protocols, referred to as Chemiflex.
Sample, anti-phenytoin coated paramagnetic microparticles, and phenytoin acridinium-labeled conjugate are combined to create a reaction mixture. The antiphenytoin coated microparticles bind to phenytoin present in the sample and to the phenytoin acridinium-labeled conjugate. After washing, pre-trigger and trigger solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative light units (RLUs). An indirect relationship exists between the amount of phenytoin in the sample and the RLUs detected by the ARCHITECT i System optics.
